    摘要： In some aspects, a method includes (i) securing multiple sets of current injecting electrodes to an organ in a patient's body, (ii) causing current to flow among the multiple sets of current injecting electrodes to generate a field in the organ, (iii) in response to current flow caused by the multiple sets of current injecting electrodes, measuring the field at each of one or more additional electrodes, (iv) determining expected signal measurements of the field inside the organ using a pre-determined model of the field, and (v) determining a position of each of the one or more additional electrodes in the organ based on the measurements made by the additional electrodes and the determined expected signal measurements of the field.

    摘要： A non-contact cardiac mapping method is disclosed that includes: (i) inserting a catheter into a heart cavity having an endocardium surface, the catheter including multiple, spatially distributed electrodes; (ii) measuring signals at the catheter electrodes in response to electrical activity in the heart cavity with the catheter spaced from the endocardium surface; and (iii) determining physiological information at multiple locations of the endocardium surface based on the measured signals and positions of the electrodes with respect to the endocardium surface. Related systems and computer programs are also disclosed.
